Hi Diane,
I see your point that the next big one would probably not be influenza and you do make a good argument with the advancement of technology and science to combat the new influenza strains attacking the human population. It is really interesting that Guinea pigs are one of the most consumed animals and are so accessible to us. Pairing that with highly contagious and airborne would definitely make it dangerous. GP virus could very much be the next type of viruses to emerge and hit humans. Have you read anything on whether something from guinea pigs has already spilled over?
